303 SW Tubeless Disc A1

Description

The Zipp 303 SW Tubeless Disc A1 is built for superior speed across every road surface—smooth pavement, broken tarmac, cobbles, gravel, and cyclocross. As Zipp’s true do-it-all performance wheelset, the 303 SW balances aerodynamics, low rolling resistance, stability, and comfort.

Its refined rim profile delivers a smoother aerodynamic transition between tire and rim, especially with wider tires. The wide stance minimizes tire deflection, lowering rolling resistance and improving efficiency. Increased tire volume allows riders to run lower pressures, reducing fatigue by smoothing out road imperfections.

Optimized around 30–35 mm tires (with best performance at 35 mm), the 303 SW’s rim shape also helps prevent pinch flats by shielding the tire during impacts. The integrated Zipp AXS Wheel Sensor provides real-time tire pressure monitoring for ultimate control. Built with the fast and durable ZR1 hubset, and backed by Zipp’s Lifetime Warranty, this wheel is ready for any road.
